Size distribution and aspect ratios of PEG-modified gold nanorods. Size distribution of PEG-modified gold nanorods treated without (A) and with (B) near-infrared pulsed laser light. Closed and open bars show the size distributions
of the short and long axes of gold nanorods, respectively. (C) Aspect ratios of PEG-modified gold nanorods without (closed bars) and with (open
bars) pulsed laser light.
